Authentic Creality Aluminum Extruder Upgrade Kit for All Creality Printers with Capricorn PTFE Teflon Tubing, Upgraded Premium Metal Bed Springs, PC4-M10 Pneumatic Fittings and Two Blue Collet Clips

Two issues I faced right out of the blocks, the hole for the screw (on the extruder arm) was not threaded, that step was forgotten and not noticed by inspectors. Ill have to tap threads into it myself. I would have simply sent the kit back to Amazon, but I had already cut and used some of the Capricorn hose.

Not worth it missing the threads to screw in tube holder. I cut the tube before I notes it was missing the threads.

Helped alot to keep the filament feed smooth and the print quality improved.

After a year of running the stock plastic extruder and tubing. I decided to change it. Ive had a couple of the plastic parts break off, suffered from some gear drag, print failure, and the small feed area where the filament enters the extruder was sharp, causing the filament to shave. Also, I discovered a crack on the bottom of the arm. In the past, Ive had excellent service and other products from F1RST LAYER, so there was no doubt where I would spend my money. The package arrived in short order and the install was simple. I would tell you to clean (learn how to) your hotend before installing the new Capricorn Bowden Tube. Its not terribly difficult. In short, turn the unit on and disable the steppers. Heat the hotend to 200 degrees, unload the filament. Remove the pneumatic fitting at the top of the hotend. Make note of how deep the tube is and match the length of the new tubing. Cut them to match. Cut at a 90-degree angle, this will ensure a proper fit and lessen the chance of leaks. Disconnect the tube connector and press the old tube into the hotend, remove any filament with a pin from inside the tube. Repeat until it is clear of filament and there is none oozing from the nozzle. Remove and replace the nozzle with a new one (not included) You should have some that were supplied with the Ender. If not clean with a brass brush and reinstall. Now, with the hotend still at 200 degrees, install one of the stainless steel pneumatic fittings. DO NOT over-tightening, but make it tight, you dont want to crack the heater block. Take the new Bowden tube and press it down through the stainless fitting into the hotend with some pressure to make it seat all the way down. Hold it there for about 15 or 20 sec so the tube heats up and seats properly. Power off the unit. Mount the Extruder according to the F1RST LAYER supplied directions. Turn the power on and heat the hotend to 200 degrees. Feed the filament into the tube while holding the feed arm you should manually extrude several mm of filament through the nozzle. Power it down and make all connections secure. Reconnect the new tubing to the wire loom just like it was, and youre done.

Good quality

Beware the springs. Make sure that you adjust the Z-axis sensor to accommodate for the extra length they provide. I wish I had noticed the sellers advice and not messed up my print bed. Other than that it is a fantastic set.

This is a bundled package of all the recommended upgrades for your Ender 3 v2 printer. I would suggest making the upgrades as you are setting up your printer. All upgrades were easily executed using only the tools that come with your printer. I did have a missing part and notified First Layer. They responded quickly and shipped out the item, plus additional items. I would strongly recommended this upgrade for its quality, convenience and customer service from First Layer.

This was a great addition to my new Ender 3 Pro. After researching the Ender 3 Pro for many months, I decided to purchase it along with a few upgrades. I figured it would be easier to go ahead and install the upgrades as I built the printer. I installed the springs first which really seemed to give much more control over the bed level. The aluminum extruder was the most complex part of the install, but overall it was a breeze. I received enough tubing to re-run the printer twice, so that was nice. Overall the kit quality was awesome and Im very satisfied with the purchase.

Great little kit for my Ender 3 Pro. Nice all-metal extruder, Improved bed springs, Capricorn tubing, and improved fittings. All in all a good step up from stock. Installed quickly, no problems, and working very well.

This is a great package of much needed upgrades. The extruder works great and helps to grip filament for smoother movement. The springs feel a little stiffer than stock ones and should keep bed stable and level longer. The Capricorn tube is a must have upgrade. You will notice an improvement the first time you print after installing it. Extrusion/retraction will be so much smoother. This is an quick and easy upgrade to make your printing better.
